  /**
   * Calculates the modulus, the remainder of an integer division.
   *
   * For matrices, the function is evaluated element wise.
   *
   * The modulus is defined as:
   *
   *     x - y * floor(x / y)
   *
   * See https://en.wikipedia.org/wiki/Modulo_operation.
   *
   * Syntax:
   *
   *    math.mod(x, y)
   *
   * Examples:
   *
   *    math.mod(8, 3)                // returns 2
   *    math.mod(11, 2)               // returns 1
   *
   *    function isOdd(x) {
   *      return math.mod(x, 2) != 0
   *    }
   *
   *    isOdd(2)                      // returns false
   *    isOdd(3)                      // returns true
   *
   * See also:
   *
   *    divide
   *
   * @param  {number | BigNumber | bigint | Fraction | Array | Matrix} x Dividend
   * @param  {number | BigNumber | bigint | Fraction | Array | Matrix} y Divisor
   * @return {number | BigNumber | bigint | Fraction | Array | Matrix} Returns the remainder of `x` divided by `y`.
